[ZNPaaneah]

11 Believe me that I am in the Father, and the Father in me: or else believe me for the very works’ sake. 12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto the Father. 13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. 14 If ye shall ask anything in my name, that will I do.

To me, this is what "the adoption of sons" is referring to. To be redeemed, forgiven, saved by grace and a child of God does not imply that "I am in the Father, and the Father in me" nor does it imply that "whatever ye shall ask in my name, that will I do".

If we view God as running a great business and Jesus has been appointed Lord of all and heir of all things. That implies that Jesus "is in the Father and the Father is in Him" and that implies that if you are in Jesus Christ, the Chief executive officer, that "whatever ye shall ask in Jesus name, that will he do".

Ps 2:7 -- This day I have begotten thee -- That is not the day of incarnation.

"This day have I begotten thee — This also is applied by some to David, understanding, by this day, the day of his inauguration, when he might be said to be begotten by God, inasmuch as he was then raised and delivered from all his calamities and troubles, which were a kind of death, and brought forth and advanced to a new kind of life, of royal state and dignity: and so this was the birth-day, though not of his person, yet of his kingdom" (Benson commentary)

Ps. 2:7 -- I will tell of the decree: Jehovah said unto me, Thou art my son; This day have I begotten thee.

"Here it refers not to a law which he was to obey, but to an ordinance or statute respecting his reign: the solemn purpose of Yahweh in regard to the kingdom which the Messiah was to set up; the constitution of his kingdom. This, as the explanation shows, implied two things:
(a) that he was to be regarded and acknowledged as his Son, or to have that rank and dignity Psalm 2:7; and

(b) that the pagan and the uttermost parts of the earth were to be given him for a possession, or that his reign was to extend over all the world Psalm 2:8." (Barnes notes on the Bible).

This "decree" is referring to the "Sonship" legally conferred. This rank includes Lord of All.
